Fish Physiol Biochem
. 2013 Nov;
15(5):413-9.
PMID: 24194301
This study deals with the variations of plasma melatonin content and ofin vitro pineal melatonin secretion, in one year-old male sea bream. Plasma melatonin levels varied from almost undetectable levels...

PMID: 21554650
Trout pineal photoreceptor cells were dissociated by trypsin-DNase digestion and further purified by a Percoll gradient centrifugation. Total cells or purified photoreceptor cells were then embedded in a collagen gel,...

PMID: 21554615
Trout pineal cells were dissociated using a trypsin-DNase digestion technique. An enriched population of photoreceptor cells was selected from a Percoll gradient centrifugation. The ability of cultured photoreceptor cells (selected...

PMID: 19215495
Abstract A suspension culture of ovine pineal cells was developed to investigate the regulation of melatonin synthesis and release. Dosedependent stimulation of melatonin release by a series of adrenergic agonists...

PMID: 10451018
In sheep, melatonin secretion occurs rapidly after the onset of darkness, but the interval fluctuates according to different authors. The aim of this study was to determine this interval in...

PMID: 10340721
In mammals, the photoperiodic information, received by the retina, is transmitted to the pineal gland. In both organs, melatonin is produced and functions as a neurohormone giving temporal information to...

PMID: 9430432
The pineal organ of vertebrates produces melatonin and adenosine. In lower vertebrates, adenosine modulates melatonin production. We report herein that 2-chloro-cyclopentyl-[3H]-adenosine ([3H]CCPA: adenosine A1 receptor agonist) and [3H]-cyclopentyl-1,3-dipropylxanthine ([3H]DPCPX: adenosine...
